. To all whom it may concern:

. features in the claims.

, my invention.

In the accompanying drawings Figure 1 is a sectional elevation of aburner embodying Fig. 2 is asectional elevation of a regenerativeburner, embodying my invention, the air under pressure being supplieddirectly into the body of the regenerator. Fig. 3 is a half plan view,partlyin section, on the line 3,3, Fig. 2looking downward and a halfplan looking upward from below the burner. Fig. 4 is a vertical sectionof a burner fitted with a regenerator to which air under pressure issupplied. Fig. 5 shows av half plan, partly in section, on the line 5, 5of Fig. 4, looking downward, and a half plan looking upward from belowthe burner. Fig. 6 is a vertical section of a burner embodying myinvention. Fig. 7 is a horizontal section on the line '7, 7 of Fig. 6.Fig. 8 is a bottom plan view thereof. Fig. 9 is a sectional elevation ofan Argand burner having my invention applied. Fig. 10 is a half plan,partly in section on the line 10, 10, of Fig. 9, looking downward, and ahalf plan looking upward from below the burner.

Referring by letter to the drawings A designates a gas supply pipe tothe end of which a burner A is attached. The burner may consist of anannular series of vertically arranged pipes a discharging into anannular chamber 0. provided with a number of nipples a as shown in Fig.2 or the gas may discharge directly into a chamber a provided withnipples a. as shown in Figs. 1 and 4 or there may be an annular chambera provided with nipples a similar to the ordinary Argand burner as shownin Fig. 9.

B is a casing surrounding the pipe Aadjacent the burner and having agreater diameter than the pipe A so that there is an air space a betweensaid pipe and the casing. Air under pressure slightly exceeding that ofthe atmosphere is introduced into this space a by any desired means. Thespace 0L5 communicates with a regenerator surrounding the burner. InFig. 1 the regenerator consists of a shell 13 surrounding the burner andhaving an annular horizontal partition of perforated material 1) nearits upper portion through which air is forced to an exit near the burnertips. I

In Fig. 2, the upper ends of the tubes at are shown as engaged in holesin a plate b which serves as a bottom to the gas chamber (1, into whichthe pipe A directly discharges. This plate I) may be integral with thewall of the chamber d. The regenerator is shown in this example ascomprising a chamber formed by a shell I) surrounding the burner. Anannular series of uptake tubes b is arranged between the shell b' andthe body of the burner. At the upper and lower ends the space betweenthese tubes b is closed in by suitable walls which may be integral withthe tubes 17 In this construction the air is forced from the space abetween the several tubes 5 and out through the annular opening b whereit mingles with the ignited gas, and a portion of air also passesbetween the pipes a to the inner side of the flame. A deflector battached to a portion depending from the tubes 19 serves to spread theflame and direct it upward through the tubes b In Fig. 4. theregenerator consists of the casing c surrounding the burner, the casinga surrounding the casing c, and the transverse vertical partitions cforming a series of chambers open at the top and bottom as plainly shownin Fig. 5. The inner ends of the partitions c are secured to the casingc and other partitions c extend from the inner side of the casing c tothe burner which serves as a support. Air under pressure is forced intothe chambers within the casing c by means of an injector c forcingatmospheric air through a pipe 0 which receives its air through theports 0 adjacent the injector.

In Fig. 6 the gas passes upward through the pipe A into a gas chamber dcommunicating with the annular row of tubes or pipes at which have thenipples a, at the lower end. An air space a formed by a casing B, asheretofore described surrounds the pipe A and has an opening at itsupper end through which the air passes and is deflected downward, by adeflector d, which may be integral with the wall of the gas chamber d,into the space between the casing B and the casing c surrounding it andbetween the tubes at to the burner tips. The burner is surrounded bycasings c 0', having the partitions c similar to the example shown inFig. 4:. The chambers for-med by the partitions 0 between the casings co serve as uptakes. The tubes at serve as conduits for the descendinggas, and the casing 0 forms a conduit for the descending air supply. Theexample shown in Fig.

6, also has a flame deflector I), supported by the casing c, whichserves to spread the flame toward the uptakes. The deflector may bestrengthened by ribs b 7 The regenerat-or shown in Fig. 9 is similar tothat shown in Fig. 4, but showing an injector communicating with an airspace a similar to that shown in Figs. 1 and 2.

In all the examples of my improvement there isa supply of air, underpressure, to the casings surrounding the burner for combustion with thegas.

In all cases there is a downwardly extending flame, and in Fig. 6 I haveshown an ascending gas supply and an ascending air supply.

Bymyinvention I obviate the use of chimneys or globes.

Having described my invention, what I claim is 1. In a regenerative gasburner, the combination with a burner for producing a downwardly oroutwardly extending gas flame, a gas conduit communicating therewith, anair conduit surrounding the gas conduit means for supplying air underpressure and an annular series of uptakes surrounding the burner,substantially as specified.

2. The combination with a burner for producing a downwardly or outwardlyextending gas flame, of an ascending and descending gas supply conduitand an ascending and descending air supply conduit, substantially asspecifled.

3. The combination with a burner having a downwardly or outwardlyextending gas flame, of an ascending and descending gas supply conduit,and an ascending and descending air supply conduit surrounding the gassupply conduit, substantially as specified.

. 4:. The combination with an annular burner having a downwardly oroutwardly extending flame, of an ascending gas supply conduit within theburner, an ascending air supply conduit surround-ing the gas supplyconduit within the burner, and a descending air conduit surrounding theburner, substantially as specified.

5. The combination with an annularburner having a downwardly oroutwardly extending flame, of an ascending gas supply conduit within theburner, an ascending air supply conduit surrounding the gas supplyconduit within the burner, a descending air conduit surrounding theburner, and an annular series of uptakes surrounding the said descendingair conduit, substantially as specified.

6. The combination with a burner for producing a downwardly or outwardlyextending gas flame, of a gas supply conduit and an ascending anddescending air supply conduit substantially as specified.

In testimony whereof I have hereunto subscribed my name this lSth day ofAugust, A. D. 1892.
